About Us

Since 1988 there have been many imitators, but only one 24® Game! Some people refer to us by other names — such as "math 24" or "24 math" — but we have always been 24 Game! We are proud of a name that represents more than three decades helping people of all ages enjoy math and discover their full potential.

The 24® Game’s simple structure allows learners to engage quickly, and almost immediately seek out higher levels of challenge. It gives children the freedom to make mistakes without being judged. The more they play, the more they engage in deep practice which leads to fluency in, and permanent retention of, critical math skills.

When playing with 24® cards competitively in a group setting, refer to these events as 24 Challenge® Tournaments. Let us help you with a Tournament! In-person event


24® Game History

In 1988, successful Engineer and inventor ROBERT SUN created the 24® Game as an innovative way to teach children the relationship between numbers through a game. The original, Single Digits cards remain a student, educator and parent favorite to this day, and have evolved into nine separate editions, covering everything from addition to algebra.

Sun's company, Suntex International Inc., was founded as an organization committed to furthering mathematics education. Suntex partnered with Council of the Great City Schools to begin a decade-long collaboration with urban school districts, and to organize "24 Challenge®" math tournaments across the US. Tournaments activate entire communities and involve parents and families in the goal to raise mathematics achievement among students.

In 2002, Sun created the internet-based First In Math® Online Program for use in schools and at home. The site's substantive content supports every curriculum and encourages practice. More than 200 K-8 online games tie into National and State standards, and include eight Skill Set® groups that provide subscribers with 24 exclusive digital editions of the 24 Game.

In 2018, 24 Game celebrated its 30th anniversary, continuing to help children sharpen basic math skills such as computation, problem solving, number sense, critical thinking, and pattern sensing.

Today, the 24 Game and the First In Math Online Program continue to help a new generation of students become critical thinkers and problem solvers.
